PURPOSE: A sub-frame mounting nut structure is provided to exclude remaining of pigment as well as non-spreading thereof at each part of sub-frame mounting nut by changing form of nut. CONSTITUTION: A sub-frame mounting nut(18) is equipped with a jig positioning hole(18a), a flange(18b) and a tapping hole(18c). In this improved mounting nut structure, the zig positioning hole is formed to be communicated with the tapping hole along the length of a body of the sub-frame mounting nut, which prevents pigment from stagnating in the zig positioning hole and gets solved non-spreading of pigment to the tapping hole.
